The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)

<h3>Trigonometric Ratios</h3>

From the given triangle ABC, we see that;

∠A = 66°

∠C = 38°

AB = 3

Thus using sine rule, we have;

AB/sin C = BC/sin A

3/sin 38 = BC/sin 66

BC = (3sin 66)/sin 38

BC = 4.45

In circle A below, chord BC and diameter DAE intersect at F. If arc CD = 46° and arc BE = 78°, what is m_BFE? D B А​
wel

Given:

Consider the below figure attached with this question.

In circle A below, chord BC and diameter DAE intersect at F.

The arc CD = 46° and arc BE = 78°.

To find:

The measure of angle BFE.

Solution:

According to intersecting chords theorem, if two chords intersect inside the circle then the angle on the intersection is the average of intercepted arcs.

Using intersecting chords theorem, we get

m\angle BFE=\dfrac{1}{2}(m(arcCD)+m(arcBE))

m\angle BFE=\dfrac{1}{2}(46^\circ+78^\circ)

m\angle BFE=\dfrac{1}{2}(124^\circ)

m\angle BFE=62^\circ

Therefore, the measure of angle BFE is 62°.
